[Long-term survival in multiple myeloma].

The authors present the results of 23-year protocol studies of survival with multiple myeloma, focused on problems of perspective long-term survival. Of 535 diagnosed patients between 1970 and 1990 the authors checked regularly and treated 475. In addition to 60 latent forms where treatment was administered only when clinical symptoms developed or after progression of laboratory signs, to all patients treatment was administered according to protocols (monotherapy-cyclophosphamide prednisone in 1970-1975 only to 30 patients, the remainder had combined treatment--COPP, VMCP, MOCCA); in the third stage of the disease MOCCA treatment is better. The median of survival of patients after VMCP treatment (in stage II) MOCCA (in stage III) is more than 90 months, 15% survive for more than 10 years. The authors emphasize the importance of combined intensive treatment of patients for the prognosis of survival. Long-term experience revealed that patients achieve an objective response in 85%, while the risk of leukaemic and cancerogenic complications is low (1.1%). The therapeutic effect and survival period are favourably affected by immunomodulation treatment (Interferon, proteolytic enzymes, thymus factor).
